Question

I’ve got a button to share an image and every times I click it, I’ve got this message in the log, I dont understand :

2012-08-12 19:21:30.511 AvisOcean[2239:707] An instance 0xe6b8fe0 of class FBSessionManualTokenCachingStrategy was deallocated while key value observers were still registered with it. Observation info was leaked, and may even become mistakenly attached to some other object. Set a breakpoint on NSKVODeallocateBreak to stop here in the debugger. Here’s the current observation info:
(

)

Any ideas?

I was having the same problem. I think what had happend is I had initialized Facebook else where and it was giving me errors when I tried to re-initialize it and again invoke a dialog delegate from a different instance.

The instance where i was keeping actual app initialization and accesstoken were different from the one which was invoking the dialog. When I corrected that after going over the documentation, it was solved.

if (nil == self.facebook) {
    self.facebook = [[Facebook alloc]
                     initWithAppId:FBSession.activeSession.appID
                     andDelegate:nil];

    // Store the Facebook session information
    self.facebook.accessToken = FBSession.activeSession.accessToken;      
    self.facebook.expirationDate = FBSession.activeSession.expirationDate;
}

[self.facebook dialog:@"feed" andParams:params andDelegate:self];
